Tellwhen makes the inbox the alert interface
Tellwhen presents an email-based service for setting web-monitoring alerts in plain language, then receiving email when something matches.
- For
- People who want web updates without checking repeatedly
- Worth noticing
- Setup emails can specify thresholds, timing, exclusions, and roundup preferences; the page says alerts can be managed by replying in plain language.
Field notes
The setup flow opens a prefilled email rather than a signup form; users describe topics, thresholds, timing, and exclusions in plain language. The page shows a sample reply organizing three alerts, including a $100M funding threshold and a daily roundup for selected research papers. It says users can revise or pause alerts by replying, and that notifications include sources. The homepage advertises free access for the first 100 people but gives no later pricing.
